Resin8's dome-it epoxy resin is an easy to use, thick epoxy resin for use in jewellery making. This low odour, two-part resin creates a high dome, has a long pot life and cures overnight.
Why choose dome-it epoxy resin?
Health & Safety
- EASY - 2:1 mix ratio by weight
- CLEAR - optically transparent with non-yellowing properties (excellent UV resistance)
- VISCOUS - creates a high dome
- SHINY - high gloss, beautiful finish
dome-it epoxy resin is a chemical and it does come with health & safety implications.
Here are the important downloads which we advise you to read before you start working with this resin:
More information on health & safety while working with epoxy resins can be read on our Health & Safety page.
- You MUST wear nitrile gloves (or use a specialist resin barrier cream on your hands)
- You MUST wear a respirator when sanding partially-cured resin
- Ensure you work with this resin in a well ventilated room
- We advise you to wear safety goggles
- Avoid skin contact
- We advise against eating, drinking or smoking while working
- In case of eye contamination wash with plenty of water for 15 minutes and consult medical advice immediately
It is CRITICAL that you follow the instructions accurately. Do NOT change the mixing ratio - this will alter the properties of the resin and cause it to remain tacky.
Use 2 parts resin (part A) to 1 part hardener (part B) by weight (2:1) to ensure a hard finish once set. Use separate, clean mixing cups for each part. We advise you to pour the hardener first and then the resin into one clean, larger cup. The mixed components should be thoroughly stirred for 3 minutes to ensure an even consistency - this is a long time... set a timer on your phone. Make sure that you mix slowly and thoroughly, scraping the sides and bottom of the mixing cup.
dome-it epoxy resin has a pot life of around 30 minutes, depending on the temperature of your workspace. Epoxy resins tend to heat up when poured in large volumes so we advise you to only mix the amount needed for use within the pot life of the product. We advise you to mix more than 50ml and no more than 200ml at one time.
This resin is designed to be used as a finishing doming layer but it can also be coloured with any non-water based pigments and powders - opaque, transparent, metallic, etc. Apply by hand pouring. Temperature should be over 18ºC (UK room temperature) and humidity level below 70% (i.e. do not use in a room with drying laundry). A 2:1 mix will provide a hard, glossy finish. Make sure your resin piece is level. Pop any bubbles by hand using a cocktail stick, or use a heat gun or naked flame for a couple of seconds to aid bubble release. Avoid dimpling by holding the blowtorch or heat gun at least 20cm away.
If cured between 20ºC and 25ºC, this resin should be cured within 24 hours. We advise you to cure your resin pieces in a dust free environment, and keep in the dark for as long as possible. The full cure will be achieved after 7 days. It is not necessary, but if desired, you can post-cure this resin to maximise its properties. Allow the product to cure at room temperature for at least 24 hours, then heat to 40°C for 1 hour, followed by 60°C for 1 hour, followed by 80°C for 3 hours. To prevent any distortion during the post-cure cycle, the part should be placed on a thick, flat tile. When post-curing is complete, let the piece cool down slowly to room temperature, preferably in a craft oven. Sudden change in temperature can cause distortion or warping.
